Do Starfish Have Eyes?

The next time you stumble across a starfish while swimming in the ocean, gaze into his arms to see if he notices you. That’s right…his arms!

Oddly enough, most starfish have primitive compound eyes on the tips of each of their arms. A recent study showed demonstrated that starfish use these eyes to process visual information, especially when there was a need to locate food sources. Two groups of starfish were studied: one group with eyes and one group without. The two groups were placed in a sandy area of the ocean and studied how they moved toward the coral reef, which was their food source. The group with eyes was able to navigate directly toward the reef, while the group without eyes wandered aimlessly.

Additional studies into starfish may help researchers learn more about eye evolution.

Researchers are also continually studying human eyes and devising new technologies to correct vision problems. For example, in the past if you were nearsighted, farsighted or had astigmatism, you were stuck wearing glasses or contact lenses for life. Today, people have options, such as LASIK laser vision correction, to potentially eliminate their need for corrective lenses.

That means swimming in the ocean (and checking out the starfish) with clear vision using just a regular snorkel/diving mask or goggles.

If seeing starfish and other sea creatures more clearly sounds attractive to you, contact Wright Vision Center at 877-576-0202 or wrightvisioncenter.com today to schedule your free LASIK Consultation. Dr. Wright isn’t an expert on starfish, but he has extensive experience in helping qualified candidates improve their vision.

LASIK vs. Contact Lenses

Many people are unaware that wearing contacts every day may be a bigger risk than having their vision corrected with LASIK.

The fact is, if you have to wear contact lenses, hard contact lenses will give you the best vision, but they are a real nuisance, uncomfortable, prone to slipping, and easily broken. Soft contacts on the other hand are more comfortable, but due to their composition and design it can be more difficult to correct astigmatism.

Possible Complications of Contact Lenses

With prolonged usage, especially in adverse environmental conditions, contact lenses can lead to:

• Cornea redness or inflammation 
• Corneal infections 
• Corneal abrasions 
• Corneal ulcers 
• Corneal swelling 
• Dry eye

LASIK eye surgery may eliminate or reduce the need for corrective lenses. As with any type of surgical procedure, there are potential risks of LASIK surgery, including:

• Dry eye syndrome
•  Visual symptoms, such as halos, glare, starbursts or double vision 
• Vision loss

Cost of LASIK

The average one-time cost of LASIK ranges from $1,600 per eye for non-customized LASIK to $2,500 per eye for customized wavefront-guided procedures. When these costs are compared to the ongoing expenses of contacts and glasses, LASIK often makes sense financially. Over any 10 year period the average vision impaired person will spend around $12,000 on:

•   New eyeglass prescriptions
• New frames and lenses 
• Replacement lenses or an endless stream of replacement contacts 
• Cleaning and sterilizing solutions

Not every person has the right eye conditions to support a LASIK procedure. If you are tired of wearing contacts or glasses and want to explore the LASIK option, the only way to determine if you are a good candidate for LASIK is by scheduling a LASIK Consultation.

Moo-ve Into Better Vision with LASIK

Did you know that July 18, 2013 is Cow Appreciation Day? In honor of this unique observance, here are a few fun facts about how cows’ eyes differ from human eyes:   

• Cow eyes are larger
• Cows cannot move their eyes like humans; they must turn their heads
• Cow eyes glow at night
• Cow eyes are oval shaped
• Cows have only black irises

At Wright Vision Center, we’re not in the business of treating cow’s eyes; however, we are in the business of correcting the human vision problems of myopia (nearsightedness), hyperopia (farsightedness) and astigmatism through LASIK eye surgery.

LASIK won’t make your eyes glow at night like cows, but it just might free you from the need for contacts or glasses. The LASIK procedure actually changes the shape of your cornea so light can be focused onto your retina properly, resulting in clear vision, even 20/20 vision, for many patients.

If you’d be interested in learning more about how you might be able to moo-ve into better vision with LASIK, contact us today to schedule your free LASIK Consultation in Rapid City. Call us today at 877-576-0202 or visit us online at wrightvisioncenter.com.

Cool Facts About Dolphin Eyes- Part 4

This is the final installment of cool facts about dolphin eyes that we learned about from Joy Clausen Soto, Senior Dolphin Trainer at SeaWorld.

“Dolphin eyes ‘glow’ at night! Just like cats and dogs, dolphins have a layer of reflective cells behind their retina which helps them see better in low light conditions.”

It would be pretty cool if we could make our patients’ eyes glow in the dark. Unfortunately, technology just doesn’t allow us to do that yet.

What we do see, however, is the ‘glow’ of many of our patients’ faces after they’ve had a successful LASIK procedure. This glow may come immediately after the procedure, when they can read a clock on the wall, or it may come several visits later when their vision has stabilized and they realize what type of freedom they now have. Not all outcomes are the same, of course, and not everyone experiences this glow.

Many people research LASIK technology and surgeons for years before making the decision to move forward. Sometimes they end up wasting a lot of time, energy and even anxiety thinking about LASIK…only to learn that they aren’t good candidates for LASIK in the first place.

Everyone has their own unique set of eyes. Even if you think you have the same eyeglass prescription as another person who had LASIK, your own genetic make-up and health conditions may preclude you from having a successful outcome. Without a detailed eye examination from an experienced LASIK surgeon, you’ll never know if you have the right conditions to possibly reverse your nearsightedness, farsightedness or astigmatism.

We hope you’ve enjoyed learning a little bit dolphins – and learning a little about LASIK along the way. We’d love to tell you more. Contact Wright Vision Center in Rapid City to schedule a LASIK Consultation and see if you’re a good candidate for LASIK. Call 877-576-0202 or visit wrightvisioncenter.com today.

Happy 4th of July!
